Specification of Letters Patent. Patented Aug, 20, 1912-.

Application filed January 30, 191'1. Serial No. 605,522.

To all whom t may concern Be it known that I, PAUL R. FLAMM, a citizenof the United States, anda resident ofthe c ity of Northv Chicago,county of Lake, and State of Illinois, have invented certain new anduseful Improvements in Valves, of which the following is alspecificat-ion.

My invention relates lto improvements in valvesespecially adapted foruse in mechan- A ics furnaces and has for its object the pro--` visionofsuch a valve of improved construction and operation. y

The invention consists in the combination and arran ements of partshereinafter described an claimed. 'i

My invention will be best understood by j reference to the accompanyingdrawings forming a part tof this specification and in t n o I i Figure 11s a perspective view of a mechanics furnace equipped with a valveembodying my invention, Fig.. 2, a section through one ofthe burners of`said furnace, Fig. 3, a top plan view of the furnace with "the coverremoved, Fig. 4, a section taken `on line az-' of Fig. 3, Fig. 5, anenlarged section through one of the supply casings employed inthefurnace, and Fig. 6, a sec; tion taken on line y-fy of Fig. 5.

The preferred form of construction as illustrated in the drawingcomprises .a suitable frame or standard 1 having a shelf 2 at one sidefor the support of soldering irons 3 as indiated. Two similar tubularburners 4 are mounted in frame 1, each of said burners being closed atits inner end by a plug 5 projecting somewhat therefrom. The burners aresupported at their, inner ends by means of a Harige 6 having recessesadapted to receive the ends `of the burners and a yoke 7 adapted toengage under the plugs 5 and be secured in clamping position by means ofa screw 8. The outer end of each of the burners is secured in positionin substantially th'e same manner in recesses provided in a ila-nge 9and by a yoke 7 and screw 8 as indicated. At its outer end each of theburners 4 lis provided with a flaring mixing chamber 10 and gas issupplied thereto through a casing 11 project-ing into mixing chamber 10and connected at theirouter ends by means cfa pipe 12. Apipe 13communicating with a main supply gas chamber 15 in one of the casings 11serves to supply both of said casings with' gas.

I Each of .thetubular casings 11 is provided with an -interiorcylindrical sealing surface 14 lying between the main supply gas chamber15 therein anda supplemental gas chamber 16 as shown in Fig. 5. Athreaded plug 17 is screwed into the end of casing 11 and is providedwith a cylindrical sealingsurface 18 coperating with surface 14 tocomplete t-he separation ofchambers 15 and 16. ,Atits inner end plug 17is provided with a valve seat 19 and in its lateral walls with radialopenings 20 leading to chamber 15. A

tubular yalve 21 is slidably mounted in each of the casings 11 andprovided at one end with a valve head 22 having a minute perforation 23therethrough and adapted to seat on valvel seat 19. Valve 21 is providedwith elongated radial openings 24 communicating with chamber 16 and isnormally held to its seat by `means of a compression spring 25 vasshown. At its inner end valve member 2l 4is provided with acomparatively large perforation or opening 26 and with side notchesadapted to receive a fork 27 on the end of one arm cfa bell-crank lever28 which is pivoted \to the chamber 10 at 29. The inner end of each ofthe bellcranks 28 rests against the bottom of a vertically Aslidablemember 30 mounted in the corresponding burner 4 and carrying a Y- shapedfork 31 at its upper end.' A suitable cover 32 is also provided forcasing 1.

In usethe gas is provided to the furnace through pipe 13,- said gaspassing freely into saidI chambers 'l5 and thence slowly throughperforations 23 to the responsive burners, the supply of gas thusprovided being merely 4sufficient to support a pilot light in each ofsaid burners. l When a soldering iron 3 is placed upon either of themembers 31, the sameis depressedand bell-crank 28 operated to withdrawvalve head 22 from its seat and permit a free iow of gas from vchamber15 vto chamber 16 and thence through' tubularl valve -member 21 to thecorresponding burner, thus supplying the heat necessary to heat saidsoldering irons.

The construction disclosed will be found highly eflicient in operationand economical to manufacture.

While I have illustrated and described the preferred construction forcarrying my invention into effect this may be varied somewhat withoutdeparting from the spirit of the invention. I, therefore, do not wish tobe limited to the precise details of construction asset forth but desireto avail myself .said chamber 15 a tubular valve 21 pro- 20 of suchlvariations and modications as comeywithin the scope ofi the appendedclaim.

Having described my invention what I 'claim'as new and desire to secureby 'L'etrs Patent is:

A valve for a meehanics 'furnace comprising a casing 11 having aninterior cylin- ,'drlcal sealing surface 14; a hollow threaded Vplug v17closing the outer end of said casing and provided with a cylindricalsealing surf face 18 Contactin with said first mentioned surface 14 anddlviding the interior of the casinglinto two chambers 15 and 16, therebeing a valve'seat 19 formed at the inner end of vsaid plug 17 and anopening 20 formed in' the slde of said plug 17, said opening 20establishing communication between the interior of said plug 17 and withvided with a valve head.22 adapted to seat on said valve seat 19, therebeing a perforation 23 in said valve head 22 and openings 24 and 26 inits side and end respectively,

, the openings 24 in its side establishing communication between theinterior of said tubular valve 21 andthe other said chamber 16; and aspring 25 arranged to hold said valve head 22' to said seat 19,substantially as described.

In `testimony whereof I have signed my name to this specification inrthe presence of EDWIN C. MEAD, vALBERT MECHAM.
